https://server1.kproxy.com/servlet/redirect.srv/sxa/sslkserupcz/s132cjg/p1/img231/409/bfg2hb4.png
but it says invalid session

any way i can find it??? i didnt save it when it was made

If the image is not there, and you don't have it saved, then the only ways to get it back would be to either find an old screenshot or something with it in, or to contact the designer who made it for you.
